| 英文摘要 | Using a recently installed system on the 13.7-m radio telescope of the Qinhai Station of Purple Mountain Observatory at Delingha, we searched for (CO)-C-12 J = 1-0 emission in a group of sources including H II region candidates,dense cores, Bok globules and pre-main sequence stars and late-type stars. The emission was detected in all the star-forming regions of different masses. The discovery of such features as large line widths, red and blue wings, variations in the core velocity and multiple emission indicates probable existence of double jets, expansion or multiple knots. The emission line was seen in two evolved late-type stars, indicating dense circumstellar gas envelopes. |
